摘要：
A compact external cavity configuration consisting of a high power gain guided laser array, a graded index lens and a mode selective mirror was investigated. The laser array was stabilised in a single spatial mode to an output power of 950 mW with 675 mW in a diffraction limited lobe under pulsed operation. The spatial mode properties of the external cavity are also correlated to thermal lasing effects in good agreement with theory. © 1990, The Institution of Electrical Engineers. All rights reserved.
